S'PEGIFIGETION forming part of Letters Patent No. 291,672, dated January8', i884.

Application filed October 4 1883. (No model.)

I0 all whom it may concern;

Be it known that I, MARTIN BoUnKn, acitizen of the United States,residing at Youngstown, in the county of ,Mahoning andState of Ohio,have invented certain new and useful Improvements in Sash- Holders; andIdo here by declare that, the following is a full, clear, and exactdescription of the same, reference being bad to the annexed drawings,making a part of thisspecifioation, and to the letters and figures ofreference marked thereon.

Figure l of the drawings is a front elevation of ,a windOw, showing myimproved sashholder connected thereto. Fig. 2 is an interior view of thesash-holder, showing the bolt drawn in from contact with the windowcasing or frame; Fig, ,3, a similar view, showing the bolt extended tobring it in contact with the window casing or frame when desired tohold, the sash stationary- Fig. 4 is a per spective View of thebolt-sections and bolt casing, or housing, showing'them disconnectedfrom each other, and Fig. 5 a detail View of the twosections of bolt,illustrating the purpose of the inclined shoulder on the slot, andshowing in dotted linestheposition of the pin immediately after passingover the shoulder.

The present invention has reference to certain new and usefulimprovements in that class of sash-holders in which is employed ahorizontal bolt formed in two sections, the in-,

her section being operated by cam-actuattwo sections, the innerbolt-section being provided with a lever extending out through thediagonal slot for operating it, by which means said section, when movedin the arc of a circle, or, in other words, partially rotated, will atthe same time be caused to move forward or outward in a horizontal line,tocome in contact with the outer bolt-section, and thus force the latterin frictional contact with the window-frame. In the above class ofsash-holders the outer section of the bolt was in no way attached to orconnected with the inner boltsection, but simply supported and retainedin operative position by the bolt casing or housing, and prevented onlyfromdropping out by the window-frame. It is the .pur- "pose of theinvention, therefore, to improve the construction of the sash holdersabove referred to, whereby the outer section of bolt is prevented fromdropping out of its casing or housing and becoming lost when the sash isremoved from the window-frame,1which ob ject I attain by a simple andeffective means of attaching the two bolt-sections together, and at thesame time admit of the inner sec tion being turned without turning theouter section, thereby providing for theaccidental dropping out andlosing the outer section of bolt when it is found necessary to removethe window-sash.

In the accompanying drawings, A represents the window-frame, and B C theupper and lower sashes thereof, to which myimproved holder is connected,in the present instance it being shown as attached to the lower sash andin position to retain it closed.

The sash-holder consists of a casing or hous ing, D, and a bolt formedin two sections, E F, the former being provided with a handlever, G, ofany suitable form and construction, by which said bolt-section isoperated. :The casing or housing D is of the ordinary construction-thatis to say, it is bottomless, and cast with an inclined or diagonal slot,or, and flanges b,for attaching it by screws to the window-sash. Itdoes, however, differ in this respect from the housings or casings abovereferred to in that it has an inclined end, a, the purpose of which willbe hereinafter described.

In the class of sash-holders hereinbefore referred to the two bolt-sections were unattached, the interior surface of the casing or housingforming a bearing for the outer section of the bolt to support it inoperative position, thus necessitating more or less friction of theparts, and when: the sash is removed in most every instance the outersection of bolt would drop from its casing or housing and too frequentlybecome lost. To remove these difficulties, in contradistinction fromhaving the two bolt-sections unattached, I attach them together in thefollowing manner: The lever G, as will be seen, extends out through theinclined or diagonal slot a, and the bolt-section E, with which thelever is integral, is .provided with a reduced end or shank, d, fromwhich projects a small pin, 6. The outer boltsection, F, is-formedhollow a portion of its length to receive the reduced end or shank d ofthe section E, the outer section also having a T-shaped open slot, f,with which engages the pin 6 in the circumferential portion thereof.

By the above-described means the two boltsections E F are attached orconnected together and prevented from being accidentally separated andthe outer section lost when removing the sash from the window-frame. Theouter section, however, can be removed from the inner section of thebolt by turning it sufficiently to bring the pin on a line with the openor longitudinal portion of the T-shaped slot. A further advantage inattaching the two bolt-sections together is that the weight of the outersection is taken from off the interior of the casing or housing, therebypreventing friction and wear of the parts, as would be the case were theouter section supported entirely by the casing or housing.

In order to take the entire weight of the lever G off the edge of theincline or diagonal slot at, and prevent too rapid wear byconstantfriction of the two, the inner end of the boltsection E throughout itsentire surface is formed inclined, as shown at g, to conform to theangle of inclination of the end 0 of the casing or housing. The twoinclined surfaces, as above described, act together as a cam to forceout or draw in the bolt-section E, and with it the outer section, F,thus notwholly depending on the action of the inclined or diagonal slota, and also'preventing wear upon the edge of the slot to that extent aswould impair its usefulness.

The outer section, E, if preferred, may be provided with abearing-plate, H, to present to the window-frame a greater frictionalsurface when brought in contact therewith. The outer bolt-section, aswell as the other parts of the sash-holder, are preferably cast ofmetal, and the plate H, if desired, may be made of wood, metal, or othersuitable material, and secured to the bolt-section in any wellknownmanner; but to facilitate the manufacture of the holders, I prefer theplate to be of metal and cast with the section, thus rendering it moredurable. The circumferential portion of the T-shaped slot f, at thepoint where it joins with the longitudinal portion or open part of saidslot, is formed with an inclined shoulder, h, as more clearly shown inFig. 5, the advantage of which is as follows: When the bolt-section E isturned sufficiently to bring the pin 6 to the extremity of the inclinedshoulder h, or at a pointindicated by full lines, by further turning thebolt-section the pin will ride over the shoulder and pass thelongitudinal portion of the slot without catching on the side thereof,therounded corner 5 guiding it to the position as indicated by dottedlines, thereby preventing any possibility of the pin catching in thelongitudinal portion of the T-shaped slotwhen the bolt-section is turnedin the direction to draw in the outer section from contact with thewindow-frame. This is an important and essential feature of myinvention, from the fact that without the inclined shoulder c, with theassistance of the rounded corner i, the pin 6 would frequently catch intheslot, as above described, resulting in the bending or twisting of thepin, and also rendering the device inoperative.

The shank d of the bolt-section E is of sufficient length, so that wheninserted in the hol-' low end of the boltsection F the shoulder formedby the reduced end of the section E will not come in contact with theedge of the outer section, a space being left, as shown in Fig. 5, thuspreventing any friction by the contacting surfaces at this point.

The bolt-section F is carried backward as well as forward by the actionof the section E, but while the said section is moved bothlongitudinally and in the arc of a circle, the

sections being provided with a lever and a shank carrying a pin, and theother section being formed hollow, and having a T-shaped slot, by whichmeans the two sections are detachably connected together, substantiallyas and for the purpose described.

2. A sash-holder'consisting of a bottomless diagonally-slotted housingcontaining a horizonal bolt formed in sections, having a handle, and ashank with pin upon one of said sections, and the other section having aT-shaped slot formed with an inclined shoulder to assist the pin inriding over and preventing it from falling in the straight or horizontalportion of the slot when the section is turned, substantially as and forthe purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
